Marc, NVO3 work is not just to repeat what we have done before. I am not aware of a specific RFC describes IRB. But as you pointed out, IRB is widely deployed in the physical networks today, but it is not in VPN bases. Please look at Microsoft hyper-v, it also implements IRB for network virtualization.
I know that the combination of L2 NVE and L3 NVE can serve some applications and it is useful, but it is not equivalent to IRB function. To support IRB function, the data plane has to perform MAC address translation and prevent the broadcast traffic in one subnet network from sending to another. There is no such requirement in current data plane requirement document. Hope this convince you a new service type of NVE.
